Symmetric Coupling Bracket for Wall Switches
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical devices, such as wall switches and sockets, face inefficiencies in installation due to multiple steps and exposed screws, leading to poor appearance and limited module size when combined in parallel.
Innovation Solution
A bracket system with symmetric coupling portions and a grounding member, integrated with a functional module and operational assembly that allows for snap-coupling and reduced component count, enabling efficient assembly and improved aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple screws are used to install the electrical device, then the functional module can be securely mounted, but the installation process becomes complex and time-consuming
Solution Approach 1:
The patent integrates the mounting function directly into the bracket structure by providing coupling portions that engage with the wall box, eliminating the need for separate screw fastening operations. The bracket body itself becomes the mounting mechanism, combining structural support and installation functions into a single component.
Solution Approach 2:
The patent extracts the screw fastening mechanism from the installation process entirely. Instead of using screws to secure the functional module, the design uses the bracket's coupling portions to directly engage with the wall box, removing the screw component and simplifying the installation to a single step.
2Reliability
If multiple screws are used to fix the cover, then the functional module is securely assembled, but the appearance quality deteriorates due to exposed screws
Solution Approach 1:
The patent combines the cover fixation function with the bracket structure through integrated coupling portions. The cover is secured to the functional module using the same coupling mechanism that mounts the bracket to the wall, eliminating the need for separate screw fasteners and hiding all fastening elements within the structure.
Solution Approach 2:
The patent removes visible screw fasteners from the final assembly by using a coupling mechanism that secures the cover without exposed fastening elements. The fixation is achieved through the bracket's coupling portions engaging with corresponding features on the cover and functional module, keeping all connection points hidden.
3Device complexity
If the functional module size is limited, then the wall switch arrangement is simple, but the adaptability for parallel arrangements deteriorates
Solution Approach 1:
The patent designs the bracket with symmetric first and second coupling portions that can engage with wall boxes in various configurations. The same bracket structure supports single-module installation and multi-module parallel arrangements, providing universal adaptability across different installation scenarios without requiring size expansion.
Solution Approach 2:
The patent uses symmetric coupling portions arranged at different locations on the bracket body, allowing the bracket to be oriented and coupled in multiple directions. This symmetric yet positionally asymmetric design enables flexible parallel arrangements while maintaining the same compact bracket size.

AI summary
Embodiments of the present disclosure provide a bracket, a functional module and a mounting method of an electrical device. The bracket described herein includes a body comprising a supporting portion adapted to support a functional component of the electrical device, a first coupling portion and a second coupling portion symmetrically arranged on the body with respect to a longitudinal axis of the supporting portion, and the second coupling portion is adapted to be coupled with the first coupling portion of a further bracket of the same specification to form a bracket set. The bracket described herein can be interlocked together, and the mounting component and the bracket are integrally formed. As a result, the appearance of the electrical device is improved, more mounting screws are saved, the mounting steps of the electrical device are reduced, and the mounting efficiency of the electrical device is improved.
